World's largest tree is wrapped in a fire-resistant blanket

The world's largest tree has been wrapped in a fire-resistant blanket as the California wildfires get ever closer. General Sherman, which stands at 275 feet, is one of a number of the giant redwoods in Sequoia National Park whose bases are being protected. The ancient trees, some of which are thousands of years old, are well adapted to fire, which can help them thrive by releasing seeds and making new clearings for saplings.
